Same, my DD when I can't ride one of the motorcycles to work (weather, kid duty, etc.).
Came from a CC 2009 Sierra 1500 with the 5.3.
Took about a week to get used to the increased length and turning radius. Better visibility with the Tremor due to tow mirrors, seat height, and camera. Almost like driving a commercial truck.
But, I've driven trucks my whole life with significant seat time in commercial vehicles and equipment, so the size wasn't intimidating.
I also live and work in the burbs and xburbs, so parking isn't an issue. If I was still in Chicagoland, things would be different. My GMC was too big for some places there.
TLDR... I love it.
